Filed: 1989-01-13
Abstract: PURPOSE:To prevent the deterioration is gradation characteristic even if there is a fluctuation in voltage by providing an arithmetic unit, calculating the correction data of a data-voltage-brightness characteristic and correcting the decrease component of the brightness level. CONSTITUTION:A video signal 19 outputted from a video processing circuit 18 is stored through an A/D converter 20 into a frame memory 17. A control section 16 of the arithmetic unit 10 receives a synchronizing clock signal 21 outputted by the circuit 18 and controls the unit 10. After the video signal input data Iij are completely inputted into the memory 17, the average values M1 to Mn of the video signal data Fij on the memory 17 of an address generat ing part 15 are determined for each of row direction j=1 to n and are held in a memory 14 for a prescribed period. Further, the video data Fmn outputted from the memory 17 are successively subjected to calculation of the correction data of the voltage-brightness characteristic possessing the input/output characteristics corresponding to the average values M1 to Mn. If the video data are corrected by this correction data, the data signal subjected to the correction of the brightness level is inputted and therefore the deterioration in gradation characteristic is prevented even if the voltage fluctuates.

Title: Time division multiplying circuit
Inventor: TORII SHIYUUICHI
IPC: G06G7/16
Filed: 1983-01-21
Abstract: PURPOSE:To make it unnecessary to combine the absolute value of an input signal on the outside of an IC and improve operation precision by dividing the voltage of an input signal inside the IC to generate the earth potential of an integrator. CONSTITUTION:Input signals Y and -Y supplied through MOS transfer gates 3a and 3b are given to the inverted input terminal of an operational amplifier 11 constituting an integrator 1 through a resistance Ri. A pair of depletion type MOSFETs Q1 and Q2 are connected in series between wirings l1 and l2 connecting input terminals 5a and 5b and transfer gates 3a and 3b. These FETs Q1 and Q2 constitute a pair of resistance elements, and signals Y and -Y voltage divided. Consequently, since the wirings l1 and l2 are adjusted to supply the potential in an intermediate level due to voltage division to the integrator 1 as the earth potential, it is unnecessary to combine the troublesome absolute values of input signals on the outside of the IC, and the precision of the earth potential is enhanced.

Title: Solenoid valve
Inventor: OSHITA MORIHITO
IPC: F16K31/06
Filed: 1993-01-21
Abstract: PURPOSE:To suppress quick motion of a valve element and reduce striking sounds by allowing a friction member furnished in the shaft/core sliding part to generate a shaft slide resistance when the valve element is contacted with a seat by a plunger with energization of a solenoid coil. CONSTITUTION:When current is fed to a solenoid coil 6 of a solenoid valve 10 for controlling the spring constant of an air suspension, a plunger 11 moves toward a base plate 18 against the action of a spring 21 owing to the attracting effect with a core 12. Thereby the valve element 19 is moved in the same direction through a shaft 17, and the valve element 19 contact a seat member 22 to generate the valve close condition. Because the shaft 17 is given an appropriate slide resistance by a friction member 22, quick motion of valve element 19 is suppressed, along with lessening of the striking sound when the element 19 contacts the seat 18b. When current feed to the solenoid coil 6 is stopped, the element 19 and plunger 11 are moved toward the core 12 by the spring 21 to generate the valve open condition.

Title: Reset signal generating circuit
Inventor: KARIYA SANEFUMI
IPC: H02H3/24
Filed: 1988-01-19
Abstract: PURPOSE:To improve the reliability of a reset signal generating circuit by boosting virtually a detection voltage of a voltage detecting circuit when a voltage value of a non-stabilized DC voltage supplied to a load has dropped due to an increase of a load current. CONSTITUTION:For instance, it is supposed that each load 7a, 7b and 7c is shifted to an operating state and a load current I has increased. As a result, a non-stabilized DC voltage VM drops, therefore, a voltage to be measured VS outputted from a connecting point of voltage dividing resistances 12a, 12b of a voltage detecting circuit 17 also drips in proportion to a drop rate of the voltage VM. On the other hand, an emitter-base voltage of a transistor 20 increases by following up an increase of the load current I, and a value of the voltage to be measured VS rises. That is, the voltage VS is corrected upward by an increase portion of the current I, and even if the voltage VM has dropped to a prescribed value, a reset signal is not outputted.
